actually I was thinking about this in the shower but wouldn't Nia's information regeneration feat technically just be limited resistance to existence erasure since all she was doing was holding off the actual erasure which eventually took effect which she never came back from unlike someone like Spawn who did come back
was thinking about it because wouldn't they give the same shit to Aku for the same logic with Ashi resisting history erasure for a week? can The Lich even bypass that?
